Summary:
This paper presents the design and fabrication of feed horn antenna integrated 380 GHz sub-harmonically pumped mixer’s split cavity block. The mixer circuit is fully integrated with the microstrip circuit and the flip-chipped diode (planar GaAs air-bridged Schottky anti-parallel diode, which was designed and fabricated by millimeter technology group, Rutherford Appleton Laboratory, UK) on suspended 50μm thick quartz substrate. The mixer’s split cavity block is designed using ANSOFT’s three-dimensional full-wave electromagnetic simulation software HFSS, as well as 3D CAD design software SOLIDWORKS. The mixer cavity and its circuit are fabricated and assembled at MMT’s Precision Development Facility, UK Rutherford Appleton Laboratory. Mixer circuit configuration and cavity block are detailed in the paper. The simulation investigation shows state-of-the-art results obtained. A best conversion loss of 6.5dB is achieved with 3mW LO power at 383 GHz.
